All composite numbers can be expressed as unique products of prime numbers. This is accomplished by dividing the original number and its factors by prime numbers until all the factors are prime. A factor tree can help you visualize this. Example: 210 210 Divide by two. 105,2 Divide by three. 35,3,2 Divide by five. 7,5,3,2 Stop. All the factors are prime. 2 x 3 x 5 x 7 = 210 That's the prime factorization of 210.
As a product of its prime factors in exponents: 2^4 times 3^2 = 144
29 is already prime. Prime numbers can't be products of primes.
As a product of its prime factors: 3*3*13 = 117 or as 3^2*13 = 117
The LCM of prime numbers is simply their product (a x b, or x*y). The least common multiple of two numbers is the product of the two numbers divided by their greatest common factor. The greatest common factor of two prime numbers is 1. Therefore, the least common multiple of two prime numbers is the two numbers multiplied together, since dividing by 1 will not change the answer. The same applies to "relatively prime" numbers such as 10 and 21, where the GCF is also 1.
How about: 2*3*5 = 30 which is the product of the 1st three prime numbers
15 is the product of two prime numbers; 3 x 5
No. 15 is the product of two prime numbers: 3 and 5
No.
As a product of its prime factors: 2*3*3 = 18
15
It is 27,000.
Yes.
30
42
No because as a product of its prime factors: 2*2*2*7 = 56
Both 3 and 5 are prime numbers. 3 x 5 = 15
